What does it mean when the engine light is yellow?

[SanJasmine]

When the engine malfunction light is yellow, it indicates that there is a problem with the engine. Here are the reasons why the engine light may be yellow: 1. Poor quality fuel or excessive engine carbon buildup: This can lead to poor combustion in the engine, potentially triggering the malfunction light. In such cases, it is advisable to promptly inspect the engine and seek maintenance at the nearest vehicle repair shop. 2. Faulty oxygen sensor in the engine: This type of issue often causes the engine malfunction light to turn yellow, but it usually does not affect normal driving. 3. Clogged fuel injectors or carbon buildup on the intake valves: These problems can trigger the malfunction light. Such issues are often related to the quality of fuel used or dust entering the engine during maintenance.
